How can Shader Graph XR be leveraged to prototype interactive lighting effects without custom code?

Answer

Shader Graph in Unity XR enables developers to prototype interactive lighting effects using a visual node-based interface, eliminating the need for custom shader code. This tool allows you to create complex shaders by connecting nodes that define the material's appearance and behavior, making it ideal for rapid prototyping in immersive environments.

<!-- BEGIN COPY / PASTE -->
    1. Open Unity and ensure the Universal Render Pipeline (URP) is configured for XR.
    2. Create a new Shader Graph by right-clicking in the Project window and selecting Create > Shader > PBR Graph.
    3. Use nodes like "Fresnel Effect," "Normal Vector," and "Emission" to simulate interactive lighting.
    4. Connect an "Input" node to capture user interactions (e.g., hand proximity) and influence lighting properties.
    5. Save and apply the Shader Graph to a material, then assign it to an object in your XR scene.
    <!-- END COPY / PASTE -->

Additional Comment:

Shader Graph supports real-time updates, allowing you to see changes immediately in the editor.
Interactive lighting can be enhanced with nodes like "Time" to create dynamic effects.
Ensure your XR setup supports URP for optimal Shader Graph performance.
Experiment with different node combinations to achieve unique lighting effects.
